Digital commissioning of a robotic production system for 3D print
Beránek, Ondřej ; Štěpánek, Vojtěch (referee) ; Vetiška, Jan (advisor)
The master thesis describes the design and digital commissioning of a robotic production system for 3D concrete printing. The theoretical part of the thesis includes an analysis of the current state of knowledge in the field of 3D printing in industrial automation. It also includes a detailed system analysis of the problem, in which the requirements and elements of the production system are specified. In the applied part of the thesis, a 3D model of the workplace was created and a simulation of the entire production process and digital commissioning of the system were performed using the ABB RobotStudio software. The output of the of the application part of the thesis is the design is the design of the workplace with a debugged control program ready for use in real operation.

Design of the dilatation pad for linear encoder
Moravanský, Richard ; Hadraba, Petr (referee) ; Štěpánek, Vojtěch (advisor)
The bachelor’s thesis deals with the issue of linear length sensors, their dividing, construction, temperature effects and design of an dilatation pad. The aim of the work is a professional search on the topic of linear length sensors, design of variants of the pad and the associated recommendation for practice. The chapter of current knowledge is dedicated to basic knowledge about position sensors, ie. converter sensor connection types. The following chapter is about the description of the basic parts of linear systems, specifically the method of drive and lead in linear systems. After clarifying the concepts, the chapter of linear length sensors will be explained. The chapter deals in more depth with position measurement in linear systems, photoelectric sensing, and a linear encoder from HEIDENHEIN. As the last part of the theory, the analysis of thermal effects is presented. The practical part describes the design of variants of dilatation pad and assembly of elements that allow expansion, their connection and clamping. In the final part, the best variant and recommendation for practice is suggested.

Using machine vision for robot guidance
Gábik, Jaroslav ; Štěpánek, Vojtěch (referee) ; Vetiška, Jan (advisor)
With the development of machine vision technologies, new applications that can increase production, versatility or simplicity of production systems are widely spread. This thesis deals with usage of machine vision for robot guidance. The task consists of creating a technique and its practical realization, where the proposed assumptions are verified. The main objective is to determine 3D position and orientation of a sheet metal part or subassembly of the body-in-white, which is lying within the reach of an industrial robot with respect to its base coordinate system. The proposed method is suitable for several types and dimensions of components, which meet certain requirements. Targeting the component is carried out by scanning significant points on the component with the help of the 3D scanner attached to the robot flange. Afterwards, gained data are processed in a designed programme. The theoretical part is focused on research in the field of machine vision, accuracy of industrial robots, compensation of their errors and manipulation and assembly of the sheet metal parts in automotive. Finally, an evaluation and recommendations for practice are provided.
